Application led February 9, 1916. Serial No. 77,162.

.certain new and useful improvements in ffiuilding-Blocks, of which thefollowing is a specification.

This inventlon relates to improvements 111 building constructionmaterial, and particu-Y larly to a form of hollow tile or brick used inconnection therewith.

The principal object of the invention is to provide a Vtile or blockhaving inter-engaging end surfaces and also means for locking the,adjoining layers together vertically, besides having cavities orrecesses formed therethrough, providing fora circulation of air andreduction of weight.

Another object is to provide means whereby a plastic lock forced betweenthe upper and lower layers of the wall, is also filled in betweenadjacent blocks in the same row. whereby the entire construction. whendry. is firmly bound and held together. and finally, to provide meanswherein that the -blocks may be further reinforced, or united b vinserted rods orV tubes so as to resist any lateral pressure caused bythe wind or oth erwise.

These and other objects, such as non-transmission of sound,prevention ofentrance of insects, and animals. the provision of highly finishedinterior surfaces susceptible of' receiving high polish` and to furnishu surface which is non-combusfible, as well as non-absorbent, areattained by the novel design and combination of the tilesI or blockshereafter described and shown iu the accompanying drawing7 in whichFigure l is a fragmental perspective view, showing the upper and sideedge ot'la block made in accordance with the invention.

Fig. 2 is a similar view looking at the. same block from the oppositeedge.

Fig. 3 is a top plan view of a complete block.

Fig. 4 is a-view showing an assemblage of blocks looking from the top,and

Fig. 5 is a broken side elevation showing an assemblage of blocks, partsbeing in section and indicating the arrangement of reinl forcing means.

While it is known that hollow tile or blocks of this description are notbroadly new, the configuration of the adjacent edges at top, bottom, andsides, as set forth, are thought to be novel, and known to be eminentlypractical.

ln the construction of the block, which is made by molding suitablematerial or composition of materials in any desired shape.y proportionand size. one of the faces as l0, may be formed against the highlyfinished surface of the mold. so as to presenta smooth and level surfacein itself without further treatment.

This may he provided for by first partially filling the. mold with acomposition capable of receivinggli smooth surface, as lime, plaster,etc.. thereafter filling in other substances for the body of the block,as sand,ashes, straw, sawdust. cinders, cork or the like. while theopposite side l1 may be formed of waterproof cement., smooth, rough,granulated or to Yrepresent stone. the composition being of a nature toresist the action of moisture or water,' or in other Words to becompletely water-proof, so that the same ma)v be used in connection withbath-rooms, kitchens, and the like, in place of expensive tilingcommonly employed.

One of the side edges as 12, is formed With a longitudinal cavityextending its entire length. semi-circular in cross section, as at 14.while the opposite side edge 16V has formed upon it a corresponding ribor projection 1?, suitedto engage Within the cavity Il. and having onits eXtreme front edge a groove. 1S for purposes further described.

lho tops and bottoms of each block are formed with level surfaces 20,which aro interrupted by grooves 21 and 22, the same being angularly.formed at the ends, as at 23 and 24, so as to meet at the center of theblock, the terminal points being in regis- YYtration with the recess 18,as previously mentloned. 1

Grooves 25 extend between the side grooves .21 and 22, connecting thesame or forming channels therebetween, so that plastic material used asa binder will flow into and completely fill the grooves or channels,portions of the Vplastic material flowing down the groove 18, fillingany cavities between the next adjacent row of blocks and which, afterhardening, form a key binding the several blocks firmly together.

Openings 26 of relatively large cross seetional area, formed in suchmanner and shape as may be desired, extend longitudinally through theblocks allowing air to l:succeeding row, the joints are broken so thatthe openings 2G are substantially in alinement, at the saine time thegrooves 18 will be in alinement with the grooves in layers of tilestherebelow. so that all openings may be readily filled b v the keymaterial. which being forced while in a plastic or semi-fluid conditionunder pressure flows in the channels and fills the grooves at the top ofthe blocks. ills the vertical grooves 1S and rising enters and fills thecorresponding grooves in the bottoni of the blocks.

From the foregoing it may be seen that a construction is provided whichis relatively inexpensive, and which may be erected without specialexperience b v common labor: that the construction is such as tocompletely prevent the transmission oi sounds. heat or cold. as well asto be impervious to the weather. and that animals and insects cannotpass therethrough, furnishing in etfect a higlrclass h vgienicconstruction, having Copies of this patent may be obtained for unusualstrength and rendering the building unusually comfortable.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

In a building block having at one end a single projecting rib, extendingits full height, and a corresponding channel in the other end of arecess formed in the extreme outer part of said rib, said block havingstraight surfaces at its upper and lower sides, a pair ot' longitudinalrecesses formed in the top andl bottoni of said blocks, each recessextending contiguously along the side edges, converging recesses jointedat theil' ouler ends with said longitudinal recesses, the. point ofconvergence heilig in register with the ends ot said rib recess,transverse recesses extendingr at intervals between said longitudinalrecesses, and openings formed through said block between said convergingrecesses and the next adjacent transverse recess and also between pairsof said transverse recesses. all substantially as shown and described. y
